I think we paid another $1000 for a second control system. We bought it in 2012 and we reused it last year and will again this year for the practice bot.

The BOM costs are practically the same for both of the robots. As for parts we make ourselves, we found the doubling the number made was not a big deal it terms of the time cost. Keep in mind we build most of our parts with a laser cutter and water jet, so for us to double our parts is not a big deal. Machined parts is a big ordeal for us and making those parts takes time. We really need to make a jig for some of those parts.

We actually save money by buying in volume in the pre-season, this cuts down on shipping costs. Right now I am looking to buy a bunch of bearings to make sure we are restocked, I making sure we have a ample quantity. Same for gears, shaft material and even wheels. a practice bot is also spare parts, so I guess we are just making sure we have enough spares.
